Service
What is software development?
Software development means designing and coding a web application, mobile app or admin panel around how your business works. Custom software comes in when ready-made programs do not cover your workflows, when several systems need to be connected to each other, or when you need to offer your customers a dedicated app.
At Agency Renaissance, software development covers needs analysis, interface design, development, testing and maintenance. Because our design team is part of the project from the start, the applications are both easy to use and in line with your brand.
Software development moves in four steps
Needs analysis
We clarify which job the software does, for whom and with which systems, and put the scope in writing.
Design and prototype
Screens and flows are designed and sent to you for approval as a clickable prototype.
Development and testing
The software is developed in parts; each stage is tested and shown to you.
Launch and maintenance
The application goes live; updates, security and technical support continue under a maintenance agreement.

FAQ
Frequently asked questions about software development
Ready-made software or custom software?
If a ready-made program meets your needs, we recommend it. Custom software makes sense when you need workflows and integrations specific to your business.
A mobile app or a web application?
We decide based on how often and on which device users will use the app; most business panels start as web applications. When needed, we can make web applications installable on a phone (PWA).
Can it connect to our existing systems?
Yes. We can connect to systems such as accounting, e-commerce, shipping and CRM through an API; the system to be connected needs to offer an API.
How do you ensure security?
In development, we build on OWASP's list of the most common web security risks, and we plan permissions and backups from the start.
How long does software development take?
It depends on the scope; after the needs analysis, we share the schedule in writing, stage by stage.
Do you provide support after launch?
Yes. With a maintenance and technical support agreement, we continue updates, bug fixes and new feature development.
